Representation of compact stars using the black string set-up

چکیده

This work is devoted to provide a way of representing $4D$ spherically symmetric and static compact stellar configurations into $5D$ space time, using the black string framework. We write four five dimensional line elements energy momentum tensor such that quantities are related by function $A(z)$, where $z$ represents extra dimension. Remarkably, one consequence our chosen form for element, fact equations reduced usual motion. Also, conservation equation adopts equation. It worth mentioning that, although methodology simple, this reduction could serve represent other types objects an dimension in future works. Furthermore, under assumptions sign pressure along given trace tensor. simple election $A(z)$ modifies some features induced 4--dimensional configuration, as mass--radius relation, inertia, central values thermodynamic variables, name few. Besides, topology model ${S}^{2}\times {S}^{1}$ not ${S}^{3}$ 5--dimensional structures.

Compact Set Representation for Information Retrieval

Conjunctive Boolean queries are a fundamental operation in web search engines. These queries can be reduced to the problem of intersecting ordered sets of integers, where each set represents the documents containing one of the query terms. But there is tension between the desire to store the lists effectively, in a compressed form, and the desire to carry out intersection operations efficiently...
